MOTOR.

SPECIFICATION forming part of Letters Patent No. 671,739, dated April 9, 1901.

Application filed September 25, 1900. Serial No. 31,057. (No model.)

To all whom. it may concern:

A Be it known that I, HENRY T.VADERs, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Motors; and I do declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- V pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to'improvements in motors, and has particular reference to that class of motors which are adapted to be operated by steam, compressed air, or any other well-known propelling medium and is designed as an improvement on a patent granted to me March 27, 1900, No. 646,197, for improvements in motors.

The invention consists in the combination and novel arrangement of the several parts of the device, as hereinafter described, illustrated in the drawings, and more particularly pointed out in the claims hereunto appended.

Referring to the drawings, Figure l is a sectional view of the motor, taken on line m Fig. 2. Fig. 2 is a view of the device, showing the relative positions of the cylinders to the exhaust-chamber and to each other and the manner of connecting the pistons of said Vcylinders to the main shaft of the motor and the position and connections of the reversinglever. Fig. 3 is a detail View showing the position of the reversing-lever when the motor is running normally ahead. Fig. 4 is avertical transverse section through the valvechest, taken on line y y, Fig. l, showing the valve mechanism. Fig. 5 shows details of the valve, reversing cut-0E plug, and mechanism for reversing said valve; and Fig. 6 is adetail sectional view showing the manner of attaching the piston-rodsof the several cylinders to the maindriving-shaft.

Referring to the drawings, the numeral l indicates the motor; 2, the several cylinders,

` having their forward ends mounted and pro- A, which exhaust-chamber is preferably circular in cross-section.

3 indicates the main shaft of the motel', being suitably mounted therein and having one end thereof projecting into the interior of the exhaust-chamber A,through the wall a thereof, said end being mounted in and centered by a bracket a. This shaft has secured on its end inside of the exhaust-chamber A a crank-arm or plate 4, to one end of which is pivoted the free ends of the piston-rods of the several cylinders 2 by placing them one upon the other and passing therethrough a securing-bolt, as shown in Fig. 6.

Loosely mounted on the main shaft, within the exhaust-chamber A, between the wall a thereof and the bracket a, is a suitable pinion b, provided with a sleeve b3, having suitable pins or projections b4, adapted to enter corresponding openings in the main valve 7 of the motor, whereby the pinion and valve will be rigidly connected, fora purpose hereinafter stated.

The numeral 6 indicates the main valveseat, which is provided with the' ports S 8 8, leading to the several cylinders, as shown, and the exhaust-port 9, surrounding the shaft 3, leading through suitable passages in the wall a down into the exhaust-chamber A. The valve 7 4is a circular revoluble sliding valve, provided with an open passage 10, adapted to open to the valve-chest ports 8 in the valve-seat. This valve is also provided with a covered passage 7', adapted to connect one or more of the ports 8 with the exhaust port 9 of the valve-seat, as is evident. In this open passage 10 is provided a suitable guide ll, as shown, upon which is slidably mounted a movable cut-od plug l2, adapted to be shifted to the opposite side of the opening l0 after the valve 7 has been turned halfway around for the purpose of reversing the engine. The object of this plug l2 is to form a movable cuto that will be operative whether the engine is moving forward or backward, and it is fitted loosely upon the guide l1 and over the valve-seat, so that some steam will escape through the crevices, and when the engine is started in the opposite direction aid in forcing said valve to the proper position on the opposite side of the IOO opening 10. After getting into this position the force of the revolving valve and friction will retain the plug in the proper position.

On the outer side of the valve 7 and projecting into the valve-chest are two oppositely-disposed pins or lugs 13 13, adapted to be engaged by a bar or pin 14, secured to or passing through the main shaft 3, as shown, for a purpose hereinafter stated. The numeral 15 indicates a suitable cap for said valve-chest, through which extends the main shaft 3 and Which is provided with a suitable inlet-pipe 16, adapted to be connected to the source of supply of any suitable propelling medium.

B is areversing-lever having one end thereof projecting through the casing and into the interior of the exhaust-chamber A and provided with a rack b', adapted to engage with the pinion b on the main shaft.

b2 is a spring having one end thereof. secured to the lever outside the casing and the opposite end secured to said casing or the support thereof for the purpose of holding said rack and lever out of engagement with said pinion until it is desired to reverse the direction of the motor.

The operation of the device is as follows: Steam, ai r, or other propelling medium enters from any suitable source of supply through the inlet-pipe 16 to the valve-chest and passing through the open passage in the valve and one of the ports 8 in the seat thereof to one of the cylinders 2 and drives the pistonhead thereof inwardly, and by reason of the connection of its piston-rod to the crank-arm or plate 4, to which the piston-rods of the other cylinders are also connected, forces the piston-heads of the remaining cylinders back, thereby expelling the expended propelling medium from said cylinders out through the ports 8 8, covered passage 7", and exhaustport 9 out into the exhaust-chamber A of the motor, whence it is taken to the atmosphere through the opening 0,2. This starts the shaft 3 to revolve and by means of the pin 14,secured therein in the valve-chest, and the pins or stops 13 13 on the valve, which are engaged thereby, will cause the said valve to revolve with said shaft, thus presenting another port 8 in the valve-seat to receive and carry to its cylinder the propelling medium, when `the same operation takes place as described for the firstcylinder. When it is desired to reverse the motor, the lever B is raised, which causes the rack b on lthe end thereof within' the eXhaust-chamberA to engage the pinion b, which is loosely mounted on the shaft 3 and connects with the valve 7. This upward movement of the lever B will turn the valvev 7 half-way around and cause the steam to enter a port 8 that would otherwise be e'X- hausting. As a consequence the movement of the engine would be reversed and the cutoff plugl2 would be immediately forced to the opposite side -of the opening 10 in thev valve 7 and perform its steam-cut-offfunction fin the same manner as if the engine were moving in the forward direction. The ends of two of the piston-rods 5 being upset and the middle piston-rod made straight, as shown in Fig. 6, the thrust of the engine is always carried upon the middle part of the p in that fastens the ends of the piston-rods to the crankshaft.
